This study is intended to develop a mentalization training program for parents with adolescents. Based on mentalization development theory and the mentalization-based treatment for adolescents and families by Fonagy and his colleagues, a program with four stages of understanding the mentalization attitude, practicing explicit mentalization, exploring mentalization inhibitory factors, and reinforcing effective mentalization was developed. 18 parents in G and P cities were recruited; the program was conducted on the experiment group and no treatment was given on the control group. According to analysis, the program had a significant effect on reducing parental non-mentalization and improving emotional regulation and relationships with adolescents, whereas there was no significant effect on certainty, interest and curiosity, which are sub-factors of mentalization. A supplementary analysis of the sessions and comments indicated that the program led parents to perceive their children as separate individuals from themselves.
 And through the process of sensitively recognizing and validating each other's emotional signals, the level of arousal can be appropriately adjusted, so that they can interact without being easily immersed in their own and children's emotions. It leads to a positive virtuous cycle of gaining empathy from children as well as restoring confidence in maintaining close relationships with children.
